Starting work as a library assistant in the latter part of the 1960s, I found books deemed to be unsuitable for displaying on the open shelves were put in a “sin bin” under the counter (Third of UK librarians asked to censor or remove books, research reveals, 20 April). Borrowers (usually male) were aware of this, and would ask the librarian if there was anything for them.
